Crystallization
The US consumes roughly 20,000–25,000 t of antimony products per year with effectively 100 % import dependency, historically on China (directly or via third countries) — a strategic lever Beijing has already pulled through export restrictions.
Technology brief
The US consumes roughly 20,000–25,000 t of antimony products per year with effectively 100 % import dependency, historically on China (directly or via third countries) — a strategic lever Beijing has already pulled through export restrictions.
The challenge
Primary use cases: antimony recovery from geothermal waters (Salton Sea and other California/Nevada hubs), underground brines, mine waters (Idaho, Montana, Nevada), tailing ponds, beneficiation-plant process brines, and spent lithium-brine streams after Li extraction.
Outputs/uses: antimony as heavy precipitate; co-recovered salts and heavy metals (Bi, As, Pb, rare elements — separated fractions); clean fresh water returned to agriculture, irrigation, industry.
Industries and users: defense/strategic stockpile, geothermal operators, lithium-brine projects, mine-water and tailings owners.
Scale: container-class, co-sited on existing water circuits.
ARBOK solution
The US consumes roughly 20,000–25,000 t of antimony products per year with effectively 100 % import dependency, historically on China (directly or via third countries) — a strategic lever Beijing has already pulled through export restrictions. The flagship domestic ore project, Stibnite (Idaho, ~60,000–70,000 t contained Sb), would cover no more than a third of consumption, and only after 2028. ARBOK's answer: antimony is hydrothermal and mobile — it prefers hot saline water to solid rock. It is permanently present in dissolved form (mg/L levels) in US underground brines, geothermal waters, mine drainage and tailings systems. Processing tens of millions of m³/year of such "liquid ore" yields metal volumes comparable to a mining operation.
> Core technology and architecture: see ARBOK-VC (Vacuum Cracking). This entry covers the antimony feedstock, market, and economics.
Per the platform: the whole aqueous stream evaporates under deep vacuum; water splits into vapor and solids, which are then separated fractionally. All heavy chemistry — antimony, bismuth, arsenic, lead, rare elements — concentrates in the final mother liquor; salts and metals precipitate in a defined sequence at specific stages of the units. No catalysts, no zinc, no sorbents, no filters. Output: clean fresh water plus metals and salts already separated from each other.
(Full mechanism: see platform entry.)
Market and application
US antimony purchases: ~$150–200 million/year. Import substitution at 10–50 % retains $15–100 million/year domestically, before water-purification credits and tens of millions of tons of clean water. Total "Made in USA" antimony turnover potential: $200–300 million+/year with a national ARBOK-cluster program. Context hook: China's export-restriction regime makes Sb a live geopolitical lever.

Scale: container-class, co-sited on existing water circuits.
Three-tier national model: (1) solid ore (Stibnite) as decade-scale baseline; (2) ARBOK on water flows — tens to hundreds of tons of Sb per site as a natural separation product; (3) refining/metallurgy feeding a US strategic reserve and allied exports.
Ideal add-on to US lithium-brine projects: post-lithium water is rich in Sb and heavy metals — a ready ARBOK feed solving three tasks at once (clean water, marketable salts, heavy-metal recovery). Cascades with ARBOK-Germanium-Gallium (geothermal waters) and mine-water cases.

Unit: 20-ft container, 200 t of underground water per day; ~0.5–0.7 kWh per ton of water (unit demand 4–5 kWh — can run on renewables or ARBOK's own water-fueled generation units).
Feed: dissolved Sb at several mg/L is a workable industrial concentration at brine-field volumes.
Resource potential: Salton Sea region alone — up to 2,000–3,000 t Sb/year (~3–4 % of the world market); 10–15 % of US consumption in a light configuration, up to 50 % with CA/NV geothermal hubs + mine waters (ID, MT, NV) + tailing ponds + beneficiation brines.
Platform vacuum separation with fractional precipitation of salts/metals along the unit train; antimony reports to the heavy final fraction. Container-class, autonomous power options. (See platform entry.)
Technical: captures dissolved Sb that reagent-based capture cannot economically reach in dilute water; co-separates Bi/As/Pb; treats brine as "liquid ore", not waste.
Economic: Sb arrives as a byproduct bonus on top of water and salt credits; water alone reaches $40/t in fracking regions.
Environmental: polluted waters become clean sources; ecology turns from a cost line into a revenue line.
Strategic: US import substitution of 10–50 % of a ~$150–200 million/year purchase bill; independence from China, Myanmar, Tajikistan.

Sb concentration variability across brine fields; selective finishing stage for Sb not documented in the source article; Stibnite ramp-up could shift import-substitution math; needs field reference on a geothermal or post-DLE stream.
